* <P>Inside Mozilla all text is encoded as Unicode. By standardizing
* on Unicode every piece of code that handles characters no longer
* needs to:
*
* Have access to a character encoding parameter.
* Ask is the data stateful?
* Ask is the data single byte?
* Ask is the data multi-byte?
* If multi-byte: have access to a routine that can
* determine how many bytes in the current character.
*
* When the document is read in a converter is used to convert
* the document's data to Unicode.
*
* nsIDocCharset provides the ability to:
*
* See what converter was used when inputting the documents
* data.
*
* Override the character set for documents where the specified
* fallback, or auto-detected character set is incorrect
